Overview

This page summarizes the Ridgecrest municipal zoning standards that govern how buildings and sites are sited and sized (setbacks, height, coverage, minimum lot/site area, density and similar rules). It is drawn from the City of Ridgecrest zoning ordinance as published in Chapter 106 - ZONING; use this as a reference but verify parcel‑specific rules with the city. For background on where zoning lives in Ridgecrest see the city's main Ridgecrest Zoning page and the district maps on the same site.

Note: I cover only development standards that appear in the retrieved zoning materials (yards, heights, coverage, lot/site area, density, special-plan/overlay rules). Where the ordinance is silent (for example, explicit FAR tables), I mark that as Not found in retrieved materials.

How to read this guide

  • First mention of related topics is linked to the internal city menu: parking, design review, overlays, ADUs, landscaping, and the state building code are linked inline below.
  • Every local requirement below is grounded to the controlling Ridgecrest code section (the § glyph plus number) and includes the file citation from the retrieved ordinance.

District-by-district development standards

Each district subsection gives purpose, typical permitted uses, the most decision-relevant dimensional standards, and where that rule appears in the code. When a district says “building height and coverage shall be as set forth in the R-1 district,” I point you to the controlling R-1 citation.

Note: where the Code delegates review to site-plan review, PUD, conditional-use or zero-lot-line procedures, I call that out (see Variances and Exceptions / Substantial Conformance citations).

  • When this page mentions parking standards, see Ridgecrest's parking rules.
  • When this page mentions design review, see Ridgecrest Design Review.
  • For overlay rules see Ridgecrest Overlay Districts.
  • For accessory dwelling unit (ADU) rules see Ridgecrest ADUs.
  • For landscaping/screening standards see Ridgecrest Landscaping and Screening.
  • For state construction measurement references consult the California Building Standards Code.

R-1 — Single‑Family Residential (§ 106-318)

  • Purpose & typical uses: One‑family residences and customary accessory uses (including ADUs subject to § 106-37). § 106-318
  • Key dimensional standards (decision-relevant):
    • Minimum site area / lot size: 6,000 sq ft. § 106-318
    • Maximum building height: 35 ft. § 106-318
    • Minimum front yard: 10 ft (driveway parking limited; setback measured from front property line; cul‑de‑sac rules apply). Minimum side yard: 5 ft (street side on corner lots 10 ft). Rear yard: 10 ft. § 106-318
    • Maximum coverage: 70% of site area (structures only). § 106-318
  • Where it applies: citywide single‑family residential zones—see § 106-318. § 106-318

Practical guidance: R-1 is the default single‑family zone; ADU proposals must follow the local ADU subsection (§ 106-37) as well as state ADU rules — see ADU link and § 106-37.

R-2 — Low Density Multifamily (§ 106-319)

  • Purpose & typical uses: Small‑scale multifamily and accessory structures; multifamily dwellings permitted with site plan review. § 106-319
  • Key dimensional standards:
    • Minimum site area per dwelling: 3,000 sq ft. § 106-319
    • Building height: 35 ft. § 106-319
    • Front setback: 20 ft (special cul‑de‑sac rules apply). Side yard typically 5 ft (street side corner 10 ft). Rear yard 10 ft. § 106-319
    • Maximum coverage: 60%. § 106-319

R-3 — Medium Density Multifamily (§ 106-320)

  • Purpose & typical uses: Medium-density multifamily; many uses require site plan review. § 106-320
  • Key dimensional standards:
    • Minimum lot/site area and frontage vary by location; many R-3 areas defer to site plan review. § 106-320
    • Front yard typically 5–15 ft depending on sub‑area; side/rear yard rules vary (some situations have zero required side/rear yards). § 106-320
    • Building height in certain commercial/mixed areas may be allowed to 60 ft where the specific plan applies — check the specific-plan rules. § 106-575

R-4 — Higher‑density Multifamily (§ 106-321)

  • Purpose & typical uses: Medium‑high multifamily, including supportive housing and SRO where allowed. § 106-321
  • Key dimensional standards:
    • Minimum site area per dwelling: 3,000 sq ft (varies by sub-provision). § 106-321
    • Building height: 35 ft (unless other plan provisions apply). § 106-321
    • Yard and coverage: front yard 20 ft (in many cases); max coverage 60%. § 106-321

RA / CEH / CHA — Residential‑Agriculture & Country Estate districts (e.g., § 106-312, § 106-313, § 106-314)

  • Purpose & typical uses: Very low-density residential and limited agricultural/animal keeping; intended for rural parcels. § 106-312, § 106-313, § 106-314
  • Key dimensional standards:
    • RA (Residential Agriculture): minimum gross site area 2½ acres; front yard 40 ft, side yards 20 ft; building height and coverage referenced to R-1. § 106-312
    • CEH (Country Estate, 2½‑acre) and CHA (Country Estate, 1‑acre) have similarly large setbacks and minimum site area rules; see those sections for precise frontage and setback numbers. § 106-313; § 106-314

E-1 / E-2 / E-3 — Estate Density Districts (§ 106-315, § 106-316, § 106-317)

  • Purpose & typical uses: Low-density residential estates with limited animals and rural character. § 106-315, § 106-316, § 106-317
  • Key dimensional standards:
    • E-1: minimum site area 10,000 sq ft; building height and coverage as in R-1; frontage and lot depth standards apply. § 106-315
    • E-2/E-3: similarly large minimum site area and front yards; see their sections for exact numbers (front yards often 20 ft or greater). § 106-316; § 106-317

RMH — Residential Mobilehome District (RMH)

  • Purpose & typical uses: Mobilehome placement and uses similar to R-1 but with RMH‑specific provisions. RMH standards adopt R-1 lot and yard minimums (see the RMH provision for additional mobilehome rules). § 106-? Not all RMH header numbers were explicit in the retrieved snippets; the RMH text states it uses the R-1 dimensional standards. Not found in retrieved materials for an explicit RMH section number; the RMH provisions appear in the zoning document and reference R-1 rules.

(Verify with the jurisdiction the exact RMH section number; the RMH text in the retrieved materials references R-1 minima but a clear § header for RMH was not consistently visible.)

Commercial and Industrial districts — selected highlights (CN, CG, CS, M-1) (§ 106-326, § 106-327, § 106-575, § 106-329)

  • CN (Neighborhood Commercial): front setback 10 ft, building height 35 ft, min site 6,000 sq ft, side/rear setbacks often 10 ft when adjacent to residential. § 106-326
  • CG (General Commercial) and CS (Service Commercial): allow denser commercial development, building heights commonly up to 60 ft in CS and certain specific plans; see the Ridgecrest Commercial Specific Plan for exact numeric standards for the plan area (Table 106-575(c)-3). § 106-575; § 106-329
  • M-1 (Light Industrial): building height 60 ft, lot depth and width minimums; yards vary depending on adjacency to residential. § 106-329

Planned Unit Development (PUD) and Specific Plans (e.g., Ridgecrest Commercial Specific Plan § 106-575)

  • PUDs allow the city to set customized open space, lot coverage, height, and parking rules as part of the final development plan; PUD may be more restrictive than the base zone (see Sec. 106-342+ and Sec. 106-347 for latitude of regulations). § 106-342; § 106-347
  • The Ridgecrest Commercial Specific Plan is codified with clear numeric rules (Table 106-575(c)-3): min parcel 10,000 sq ft, max building height 60 ft, front setback 5 ft (but 10 ft where abutting residential; 20 ft at the southern boundary), side/rear setbacks 0–20 ft depending on abutting conditions, and explicit notes about measurement (height measured pad-to-parapet; parapet exclusions called out). § 106-575 (Table 106-575(c)-3)

Important practical note: the specific plan explicitly states building height measurement conventions (pad elevation to top of parapet; architectural features excluded) — use that when calculating allowable height in the plan area. § 106-575

(For full tables and special-use requirements consult the cited §. Where a district refers to “building height and coverage shall be as set forth in the R-1 district,” that means the R-1 numbers apply by reference — see the applicable §. Multiple sections in the code cross‑reference other districts; read the district header for the authoritative rule.)

Checklist (what an applicant must satisfy)

  • Confirm the property’s zoning district and any overlays; consult Chapter 106 - ZONING and the zoning map. § 106-1
  • Verify permitted use in the target district and whether the proposal requires a conditional use, PUD, or site plan review. (See the district's permitted/conditional use lists.) e.g., § 106-318, § 106-319, § 106-575.
  • Confirm setbacks (front, side, rear), lot coverage, min lot area, and maximum height from the district section that applies (use the table above as a quick check). e.g., § 106-318, § 106-319.
  • If the site is in the Ridgecrest Commercial Specific Plan area, obey Table 106-575(c)-3 and the plan’s measurement rules (height measured pad to parapet). § 106-575
  • Meet on‑site circulation and parking requirements (consult Ridgecrest’s parking chapter and specific‑plan parking notes). § 106-575; see Ridgecrest Parking.
  • If proposing an ADU, check § 106-37 for local ADU rules (setbacks, height caps, parking carve-outs) and reconcile with state ADU law. § 106-37
  • Confirm whether design review or site plan review applies; prepare elevations, materials, and landscape plans for review per the design-review rules. See Ridgecrest Design Review and Ridgecrest Landscaping and Screening.
  • For zero lot line or PUD options, submit conditional-use or final development plan per the corresponding sections and be prepared for additional conditions. Secs. 106-436—106-439 and 106-342—106-348.

Risks & Ambiguities

Issue Why it matters What to verify
FAR / Floor Area Ratio The Ridgecrest zoning excerpts and specific-plan material do not publish a citywide FAR table. Projects that rely on FAR to calculate bulk can be ambiguous. FAR: Not found in retrieved materials — verify with planning staff and project planner.
RMH section number RMH rules reference R‑1 minima but the clear header/section number for RMH in the retrieved text was not unambiguously present. Confirm the RMH section number and any RMH-specific exceptions with the planning department.
ADU local vs. state preemption State ADU law limits local restrictions; local § 106-37 confirms many ADU rules but local practice may still impose conditions. Cross-check local ADU provisions (§ 106-37) with California ADU law; when in conflict, state law may control. § 106-37; California ADU law.
Height measurement conventions in specific‑plan areas Measurement rules differ (pad-to-parapet; architectural features excluded) — mis-measuring height can produce an oversized design. Use the Ridgecrest Commercial Specific Plan Table 106-575(c)-3 measurement note and confirm base pad elevation with Public Services Director. § 106-575
Site-specific easements/CC&Rs Some setbacks are measured to easements or rights-of-way; existing CC&Rs or easements may alter allowed placement. Obtain title report and utility easement plats; verify whether any adopted subdivision standards override Code minima (the Code allows subdivision-approved standards to govern). § 106-? (Conflicts & subdivision cross-reference)
Interpreting “as set forth in R‑1” cross-references Several districts adopt R‑1 height/coverage by reference; failing to trace that reference can lead to mistakes. Track each district’s cross reference to the exact R‑1 paragraph you rely on (e.g., § 106-318).

Plain-English Summary

Ridgecrest’s zoning (Chapter 106) sets the basic siting and size rules: single‑family lots (R‑1) typically allow up to 35 feet tall homes, 10–20 foot front yards depending on district, 5–10 foot side yards, and coverage limits that vary by zone (commonly 60–70%). Commercial specific-plan areas and PUDs have their own tables (Table 106-575(c)-3) that supersede the base rules where applied; always cite the exact § for your lot and check for overlays, PUD conditions, or zero‑lot‑line options before designing.

Frequently asked questions

What can I build on an R-1 lot in Ridgecrest?

You can build a one‑family dwelling and customary accessory structures; accessory dwelling units (ADUs) are allowed subject to § 106-37 and local ADU rules. For R‑1 dimensional limits (height, setbacks, coverage, min lot area) see § 106-318.

What are Ridgecrest setback requirements for single‑family homes?

Ridgecrest’s R‑1 setback basics: front yard 10 ft, side yards usually 5 ft (street side corner 10 ft), rear yard 10 ft; driveway/parking in front setbacks is restricted per the district. See § 106-318 for full rules and cul‑de‑sac exceptions.

How tall can I build in Ridgecrest?

Standard residential districts commonly cap building height at 35 ft (R‑1 through R‑4); certain commercial or industrial zones and specific‑plan areas can go up to 60 ft per their sections (for example, Table 106-575(c)-3 for the Ridgecrest Commercial Specific Plan). Always verify which district or plan applies to the parcel. See § 106-318 and § 106-575.

Does Ridgecrest regulate lot coverage and density?

Yes — districts publish maximum coverage and minimal site area/density (for example, R‑1 coverage 70%, R‑2 60%, many districts list min site area per dwelling). See your district’s section (e.g., § 106-318, § 106-319) for exact percentages and the specific plan for its own coverage rules.

Are there special rules for commercial projects in Ridgecrest?

Yes — the Ridgecrest Commercial Specific Plan (codified at § 106-575) sets a separate development standard table (minimum parcel, setbacks, building height, landscaping, parking and loading rules) that supersedes or supplements base zoning for that plan area; follow Table 106-575(c)-3.

Do I need design review or site plan review for my project?

Many non‑single‑family uses, multi‑unit projects, and specific‑plan outlots require site plan or design review; the Code specifies which uses require review in each district (see the site plan review callouts in the district sections and Ridgecrest Design Review). Check the specific district (e.g., § 106-319, § 106-320) for triggers.

Can I build a detached ADU with 4‑ft side/rear setbacks?

Local ADU rules reference four‑foot setbacks for certain detached ADUs consistent with state ADU law; see the ADU subsection § 106-37 and be aware of state ADU preemption. Check both local § 106-37 and state ADU law (California ADU law).

How is building height measured in the Ridgecrest Commercial Specific Plan?

The specific plan spells out height measurement: height is measured from the finished pad elevation to the top of parapet and may exclude some architectural features — follow Table 106-575(c)-3 note. § 106-575.

What if my lot is in a PUD or has a zero‑lot‑line proposal?

PUDs and zero‑lot‑line developments are processed under separate sections (PUD standards and final development plan rules; zero‑lot‑line conditional use procedures). The planning commission or public services director may impose stricter standards; see § 106-342+ (PUD) and § 106-436—106-439 (zero lot line).

Is there a single FAR number I can use across the city?

No. The retrieved zoning materials do not publish a citywide FAR table; many standards are expressed as lot coverage, unit density, or by specific-plan numeric limits. FAR: Not found in retrieved materials — verify with planning staff if you need FAR for an entitlement.
